I'm using it without data loss incidents for over 1.5 years now. On SSD drive I have encrypted volume. On top of it I have LVM volume. Ot top of it BTRFS partition. I use compress-force=lzo,autodefrag mount options. Works well for personal computer use case. I always follow latest kernel from Debian backports repo. I red that some RAID modes are implemented poorly it BTRFS still.
